Stanford University in Stanford, CA, is being awarded a $13.1 million cost contract for R&D to design, build, calibrate, test, and deliver a flight-qualified very low frequency receiver and ...

The Air Force is looking for the next generation of Very Low Frequency communications to maintain contact with its ICBMs and bombers. In particular, the Air Force wants to address the problem that ...

North Pole High School math teacher Dr. Curt Szuberla and his student team of aspiring scientists and engineers braved the elements this winter on NASA’s behalf to scout locations for and build a very ...

The very low frequencies (VLF) are located between a few kilohertz and around 300 kHz, depending on whose definition is used. For purposes of this chapter VLF represents the 5- to 100-kHz region. The ...

HANSCOM AIR FORCE BASE, Mass. – U.S. Air Force researchers are searching industry for new enabling technologies that could help upgrade very low frequency (VLF) and low frequency (LF) radio ...

WASHINGTON (Army News Service) -- The Defense Advanced Research Projects Agency is working now to develop a backup system to be used by service members in the event that access to the Global ...

Military communications experts at the Rockwell Collins Government Systems segment in Cedar Rapids, Iowa, are starting full-rate production of a secure and jam-resistant very low frequency (VLF) radio ...

Here is a VLF receiver tuned to 300 kHz designed to detect the crackle of approaching lightning. A bright lamp flashes in sychrony with the lightning bolts indicating the proximity and intensity of ...

If you need to generate a radio frequency electrical signal, you will make some form of electronic oscillator. We’ll probably all be used to oscillators using transistors, tubes, logic gates or a host ...

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The proposal seeks funding to investigate quantitatively the lightning-induced electron precipitation ...
